Yunyan passed her Ph. D. defense on May 19th, 2006.  The title of her dissertation is "On the Application of Mixed-Layer Model to the Stratocumulus-Topped Boundary Layer."  She is currently (June--October 2006) working as a post-doc with Michael and with Bjorn Stevens.  In August, she accepted a post-doctoral job offer from Lawrence Livermore National Lab to work with Dr. Steve Klein in the PCMDI group.   The project she will work on is to evaluate and improve the cloud-resolving model (CRM) component of the multi-scale modeling framework (MMF).  She and her family plan to start their new life in Livermore, California, in October. William Weisong Zhai, Yunyan's little son, is now twenty months old.  He is learning to speak, still in Chinese, but will soon pick up English, too. You can see picture of proud parents here.
